Many companies have their annual appraisal & pay hike once a year at a fixed time. Let's say for a company it happens in January of every year.
How are employees who join at different times handled. For e.g. if there is an employee who joined in September, then Jan may be too soon for an appraisal & a hike. However, if it is skipped totally, then his first appraisal would be 16 months after he joined. How is this handled?
